We have a 1988 Catalina 30 with the dinette salon table. I'd like to make another table top that I can swap out with the original table on occasion. Does anyone know of a source for the bracket (socket, clamp or whatever it's called). The thing I'm looking for is the bracket or socket which is bolted directly to the bottom of the table, which clamps onto the 3-1/2 inch diam. pedestal post. There is a similar bracket attached to the cabin sole. Anyone know where to order one?Regards,Gary Kunkel
